Chronically implantable wireless neural interface devices require biocompatible and stable high density integration of several components such as sensing elements, data processors, communication, and power supply coils. Biocompatible integration technology has been developed for Utah Electrode Array (UEA) based implantable neural interface devices. These interface devices comprise: silicon base...

Materials and device designs are presented for electronic systems that undergo functional transformation by a controlled time sequence in the dissolution of active materials and/or encapsulation layers. Demonstration examples include various biocompatible, multifunctional systems with autonomous behavior defined by materials selection and layout.

Mechanical and biological biocompatibility is important consideration for materials that are used as metallic implants. During the past two decades, many β-type titanium alloys composed of non-toxic and hypoallergenic elements with low Young’s moduli have been developed worldwide. Recently, the development of new titanium-based materials to improve the mechanical and biological biocompatibility...

This paper describes the functionalization of magnetoelastic (ME) materials with Parylene-C coating to improve the surface reactivity to cellular response. Previous study has demonstrated that vibrating ME materials were capable of modulating cellular adhesion when activated by an externally applied AC magnetic field. However, since ME materials are not inherently biocompatible, surface modific...

The development of a method for integrating highly efficient energy conversion materials onto stretchable, biocompatible rubbers could yield breakthroughs in implantable or wearable energy harvesting systems. Being electromechanically coupled, piezoelectric crystals represent a particularly interesting subset of smart materials that function as sensors/actuators, bioMEMS devices, and energy con...

The most-popular root canal filling materials for primary teeth are zinc oxide eugenol (ZOE), iodoform paste, and calcium hydroxide. Root canal filling materials need to be biocompatible with the periapical tissue. There are few papers which indicate the mechanism of cellular change of root canal filling materials. The purpose of the present study was to evaluate the cellular changes of a ZOE w...
